HEADLIGHT.

Specification of Letters Patent.

Application filed May 3, 1909. Serial No. 493,460.

To all whom it may concern:

Be it known that I, RICHARD H. WELLES, 'acitizen of the United States,residing at the city of Kenosha, county of Kenosha, and State ofWisconsin, have invented certain new and useful Im rovements in Headlights, ofwhich the fo lowingis a specification.

This invention relates to improvements in headlights and refers morespecifically to improvements in headlights. of that type which areemployed for lighting the roadway in advance of vehicles, boats, etc.,the particular embodiment shown beingsuitable for use in-connection withautomobiles.

Among .the salient objects of the invention are to provide aconstruction inwhich the parallel ray beam may be temporarily eliminatedor dispersed; tgprovide a construction in which the directlon of thenormal light of the lamp may be so changed as to eliminate or modify theglare due to the parallel or approximately parallel rays; to provide abeam of parallel or approximately parallelrays; to provide aconstruction 1n which the above objects may be accomplished by simplyshifting the nozzle or. burner out of the normal focus of the lamp; toprovide a construction in which the burners of two or more headlightsmay be simultaneously shifted into or out of focus at will toaccompl'ish thepurpose referred to;

to provide a slmple, inexpensive and efi'ec.-. tive construction whichcan be readily af.

fixed to any well known type of lamp or headlight; and in general "toprovide an improved construction of the character referred to.

The invention consists in the matters here-' with my invention. Fig. 2is a fragmentary vertical sectional. view taken approximately at rightangles to the view shown in :Fig. 1..

Fig. 3 is a perspective view of the front end of an automobile showingtwo headlights in place thereon equipped with my invention, v

' In headlights as now commonly organized for use in connection withautomobiles, locomotives, boats, etc., the light is so reflected as toform a parallel ray beam. When an automobile is approaching an object,it is desirable to'modify or lessen the glare of the light from theheadlights by dispersing or changing the direction of the beam. Iaccomplish this by temporarily shifting the burner out of the normalfocus of the lamp.

Referring to the drawings, 1 designates as a whole the headlight casingwhich is shown as consisting of a cylindric side wall member 2, aflaringfront rim 3 and an outwardly convex rear end wall 4. Seated int-he rearend of the casing is av reflector 5 of that type known as Mangan mirror;this re- I flector being of well known construction and serving to notonly reflect the rays but to modify their direction so that the raysemanating from the focal point of the lamp are reflected and at the sametime brought into parallelism with each other. For the protection of theinterior parts of the headlight the front end of the casing is closed bya plain glass or crystal 6, which, as shown, is made of'uniformthickness throughout and therefore does not Substantially vary thedirection of the rays passing therethrou h.

7 designates the nozzle or burner which as usual enters through anaperture 11 burner in this instance is an acetylene .gas

burner and a gas sup 1y pipe or tubeis connected. with the capltal 30.0fthe. nozzle at the lower end of the'latterin a well known manner. Thenozzle isso mounted that it may be shifted above theJ-focal point of thelamp'. To this end a centrally apertured block.8 is soldered orotherwise secured to thelower side of the casing and is .formed in thelower side of the headlight internally screw threaded as shown at 9. toreceive and hold a tubular socketmember or burner housing 10 throughwhich the nozzle extends. The aperture 11 in the 'casingis of slightlyless diameter than the .corre bular guide carried by the casing, amember move the said slidably mounted member slidably mounted within thetubular guide and throw the flame from the focus of the a burner tipcarried by the said member and reflector. normally being in such aposition that the RICHARD H. \VELLES. flame is at the focus of thereflector, a lever Witnesses:
